F30630 SI P2: Brake control error
Message class: Safety monitoring channel has identified an error (10)
Reaction: OFF2
Acknowledge: IMMEDIATELY (POWER ON)
Cause: The "Safety Integrated" function integrated in the drive on processor 2 (P2) has detected a brake control error and
initiated a STOP A.
- motor cable is not shielded correctly.
- defect in the Safe Brake Module, in the Power Module or in the Control Unit.
Fault value (r0949, interpret decimal):
10:
Fault in "open holding brake" operation.
- parameter p1278 incorrectly set.
- no brake connected or wire breakage (check whether brake releases for p1278 = 1 and p9602/p9802 = 0 (SBC
deactivated)).
- ground fault in brake cable.
30:
Fault in "close holding brake" operation.
- no brake connected or wire breakage (check whether brake releases for p1278 = 1 and p9602/p9802 = 0 (SBC
deactivated)).
- short-circuit in brake winding.
40:
Fault in "brake closed" state.
60, 70:
Fault in the brake control circuit of processor 1 or communication error between processor 1 and processor 2 (brake
control diagnostics).
Remedy: - check parameter p1278 (for SBC, only p1278 = 0 is permissible).
- select Safe Torque Off and de-select again.
- check the motor holding brake connection.
- check the function of the motor holding brake.
- check the Safe Brake Module connection.
- check that the electrical cabinet design and cable routing are in compliance with EMC regulations (e.g. shield of the
motor cable and brake conductors are connected with the shield connecting plate and the motor connectors are
tightly screwed to the housing).
- replace the Safe Brake Module.
- replace Power Module.
- replace the Control Unit.
Note:
SBC: Safe Brake Control
SI: Safety Integrated
F30649 SI P2: Internal software error
Message class: Hardware/software error (1)
Reaction: OFF2
Acknowledge: IMMEDIATELY (POWER ON)
Cause: An internal error in the Safety Integrated software on processor 2 has occurred.
Note:
This fault results in a STOP A that cannot be acknowledged.
Fault value (r0949, interpret hexadecimal):
Only for internal Siemens troubleshooting.
Remedy: - carry out a POWER ON (switch-off/switch-on).
- re-commission the "Safety Integrated" function and carry out a POWER ON.
- contact Technical Support.
- replace Control Unit.
